Hi Brian-

The fill val is a global attribute, specified as:
:Fill_Value = 9.96921e+36f ;
:missing_value = 9.96921e+36f ;
So the macro is expanded, but without underscores.
do I need (2) underscores, and must the fillval be associated
with a variable?
Yes, the convention is that the _FillValue attribute
be associated with each variable. Using it as a global
variable does not work. We prefer to use the attribute
missing_value, but either is acceptable. See the netCDF
best practices page:

section on missing data for a little more info.
